Salmon and Trout - Differences and Similarities

Belonging to the same Salmonidae family, both the salmon and the trout are classified as oily fish and used for culinary purposes. The only difference in the two types of fishes is their natural habitat. Salmon species live in saltwater most of their lives while trout live in fresh water. Not surprisingly, salmon tends to have a much stronger flavor, whereas trout is relatively mild. Most recipes for salmon go well for trout and vice versa. However, here is also a special selection for trout recipes.

Based on the surroundings, the different patterns and colorations of trout serve as camouflage. The ability to change their pattern and color is a characteristic of trout as they move from one habitat to the other. Their change in appearance can also signify that they are ready to find a mate and reproduce.

Salmon, on the other hand, live in the cold seawater and fresh water in the North Atlantic and North Pacific Oceans. They are known as animals that travel thousands of kilometers after they are hatched. From the rivers and streams where they were hatched, they travel to the ocean to feed and grow then trace back their route to the freshwater habitat where they were born in order to reproduce.

In North America, salmon is considered one of the most popular edible fishes because of its versatility in any cooking methods. It can be grilled, smoked, cured, baked or served as sashimi.

Salmon has gained the reputation of being the “omega fish” because of its high content of omega 3 fatty acids. These fatty acids are in an unsaturated form and have been proven to improve cardiovascular health and reduce the risk of heart diseases. It is also rich in vitamin D and protein which are both beneficial to humans.

All over the world, salmon is considered a main food for humans. Some people even eat the eggs or used as bait by those who are into fish sports. As a matter of fact, the salmon industry generates millions of dollars a year by shipping fresh and frozen salmon around the globe.

Salmon is not only food for humans but animals, too. During their journey back to their freshwater habitat, they are eaten by bears, bald eagles, and other mammals and birds. Even those that die after spawning serve as food for the small arthropods that live in and around the rivers and streams.

In the middle part of the 20th century, the population of the wild salmon has greatly decreased in number because of overfishing, rising temperatures of the ocean and construction of irrigations and dams. To prevent further decline in population, several policies were enacted to protect the wild salmon. For instance, fish farming is no longer allowed in Alaska resulting to a thriving population of Alaska’s salmon until the present times.
Each year, many salmon die in their attempt to travel up rivers and streams back to their freshwater habitat. The major cause of death is trying to get past dams. As a solution to the problem, fish ladders are designed to help salmon go through dams safely and save a large number of salmon from dying.

Fish hatcheries are also put up to help in the survival of salmon species. Valuable eggs are hatched and raised in nurseries then released back into the river when they are already large enough to survive on their own. Conservation efforts like passing laws to protect salmon and help restore their natural habitat are done by some governments to prevent these valuable fish species from disappearing.
